rIhis invention refers tov means for. ther` .,nianul'acture of wooden articlesY especially such articles as boxes, orl similar bodies. Notwithstandingnthe invention will'be `described here below assuited ior a peculiar branchV of manuacture-the producing of;

corners of packing boXes-Iwant to 'declare that my improvedto'ol is not limited ato this special'work, but can bereadilynsed in; any

joiners shop or elsewhere where is thevneed of attaching woodenjpieces togetherto form acorner. Y f

Y The main object of this invention. is A:to

The tool comprises a base 1 inthe'shape vof,

= 15, V15 a Ufshaped aperture 18 passes through the plate 8. The position and-size of aperture 18 are chosen so, that theone lefg v18 of 'the :U registers Vwith the a erture 2 in basel when the plate 8 is turned into its one end position in relation tobase 1 (Fig. 4), and the other. leg 18 yof saidU registers switlrthe same aperture :2 when the plate 8 isturne'd v into itsreverse end position (Fig. 5).

ln Athe first mentionedposition the, toolis adapted'to` be used for the joining offright hand corners'in for insta-nce' a rectangular yframeof the type illustrated in"f*`g.i (5,'and

in the v'last `ment-ioned position the to`olis adapted for the same coaction witlia left Vhand `co1"ner. 'gTo clearly demonstrate the two differentdispositions the above mentioned dot-and-dishglines in Figs. 4 and^5 i aredesignated with the numbers 21,21 and 22, `22 in correspondence with tliefvarious members of the frame inqFig. G; v

, I will now'explain 'fl'rowthe tool may be .used when joining the corners ofthe Vtrame Vexenfipliliedin Fig. 6. The platev Sristurned `into the position shown in Fig. 5 and secured bythe set screw 12 and wing-init 11. zInlthis conditionv 'the tool Vis lplaced vabove *a kleft handcorner 420er 20 in theI frameshown in Figz since the yt'wo members 522,721. (22', 21)ff have ybeen broughtclose together for assembling. A fastening member 3 is" supplied-to`the sleeve 4 and` the set-5 inserted thereabove. On account of the position `f t'lieplateV 8"the leg 18` of its aperture l18 register with-the aperture l2in base 1, 'so that the-member 3 can `be driven 'out of the sleeve 4 ldownintot'he registering corner of the members 21, 22 (21', 22) whenaasufficient' powerful blow of a yhammer is applied ontheheadA 6 the resultbeing a. joining of said corner 2O A(20). Now thetool is removed from the frame, the plate 8 turned into its reverse end position (Fig. 4) vand secured by the set screw 12 and wing nut 11. Y

The .tool is now adjusted for a right hand corner 19 or 19, and disposed accordingly since such a corner has been prepared by placing the necessary members 21, 22 (21,

22) .in proper position.y A new member 3 is I want to express, that I do `not Wish to 1 limit myself to exclusively the outer appearance or design of the tool exemplified `in the.` annexed drawing, but the same may be varied within the scope of inventionas set forth in the .accompanying claims so as tosuit fany desired V-appeara'nceof the work Vpiece to betreated. 'Especially the cross section of the sleeve 4 vandksetl as well as the shapeof the apertures2 and 18.as also the form and sizes of lugs 14-17 may -be varied innumerallyas to the design of the workpiece.

Having thus described and shown -my inF vention and-how itis to be perforn'ied, what I claim as new and do protect' by Letters Patent is: Y Y

A tool for l'joining corners of wooden articles comprising` in combination a sleeve shaped tojguide bar shaped fastening-niembers provided to be driven into thecorners in the length direction of the-joint, aset reciprocable in said sleeve to force said fastening members outof said-sleeve, a basev for said sleeve having Van aperture through which said members canbe driven lout from saidv sleeve, and lugs to Control the proper position ofthe tool in the corneito be joined, said lugs being shiftableV so vvas, to make the tool suitl left hand cornersr as 'Well as right hand corners. e In testimony whereoffl have affixed m signature.
